OBJECTIVE We describe the sonographic findings of nasal fracture in children, and we evaluate the diagnostic value of sonography as compared with conventional radiography and clinical findings to determine whether sonography can be a primary technique for evaluating nasal fracture in children. MATERIALS AND METHODS Conventional radiographs and sonographic(More)
OBJECTIVE To evaluate the prevalence of known risk factors for contrast-induced nephropathy (CIN) and their association with the actual occurrence of CIN in patients undergoing intravenous contrast-enhanced computed tomography (CECT) in Korea. MATERIALS AND METHODS Patients who underwent CECT in 2008 were identified in the electronic medical records of 16(More)
We evaluated the US findings in acute idiopathic scrotal edema (AISE) in order to identify diagnostic features that may help to avoid unnecessary surgical intervention. We investigated 12 boys with AISE diagnosed according to the clinical course and US findings. We assessed the thickness, compressibility, and vascularity of the scrotal wall, the extent of(More)
Abdominal CTs of 57 patients with bowel perforation after blunt abdominal trauma were retrospectively analyzed to determine: the diagnostic accuracy of the perforation site, and the differential findings according to the elapsed time from the trauma. Diagnostic accuracy of the perforation site was as follows: duodenum (100%), jejunum (81%), jejunoileal(More)
OBJECTIVES The purpose of this study was to evaluate the additional value of supplementary computed tomography (CT) after sonography for diagnosing acute appendicitis. METHODS Among 140 consecutive patients with suspected acute appendicitis who underwent both initial sonography and supplementary CT within 12 hours, 88 patients whose appendices could not(More)
OBJECTIVE We prospectively evaluated transabdominal and transvaginal sonographic findings of patients with pelvic congestion syndrome and compared them with those of healthy volunteers. SUBJECTS AND METHODS. We examined 32 patients with pelvic congestion syndrome and 35 control subjects. Using transabdominal sonography, we evaluated the ovarian veins for(More)
OBJECTIVE To evaluate the Doppler sonographic findings of the left renal vein in children with orthostatic proteinuria in comparison with healthy children and to propose more reliable sonographic criteria for diagnosing nutcracker syndrome in children. METHODS Doppler sonographic findings in 47 children with orthostatic proteinuria and in 27 healthy(More)
Pseudoaneurysm of the femoral artery after internal fixation of a trochanteric fracture is caused primarily by overpenetration of the drill bit or screws. We report a case of pseudoaneurysm of the superficial femoral artery after insertion of a Gamma nail. A probable cause for this injury is adduction and internal rotation of the involved limb. During the(More)
OBJECTIVES The purpose of this study was to retrospectively evaluate the sonographic findings compared with magnetic resonance (MR) arthrographic and arthroscopic findings in diagnosis of anterosuperior labral tears of the hip. METHODS The Ethics Committees of our institution did not require patient approval or informed consent for this retrospective(More)
OBJECTIVE The purpose of this article is to determine whether bright rim lesions on MRI are a marker for anterior talofibular ligament injury. MATERIALS AND METHODS The study included 34 patients who had an ankle injury and underwent arthroscopic surgery. All patients underwent 3-T MRI for the diagnosis of anterior talofibular ligament injury. If MRI(More)
